Description

Technical Field

[0001] The present invention relates to the technical field of concrete slab pressing, and specifically to an autoclaved aerated concrete slab pressing and forming device and a forming method. Background Art

[0002] Autoclaved aerated concrete slabs are a kind of green and environment-friendly building material with cement, lime, silica sand and other siliceous materials as the main raw materials, and different numbers of anticorrosive-treated steel mesh sheets are configured and added according to structural requirements. It forms porous crystals through high temperature, high pressure and steam curing, and has good fire resistance, fire prevention, sound insulation, heat insulation, heat preservation and other properties. However, when pressing the precast concrete with a pressing plate, it is necessary to ensure that there is no shaking when the pressing plate moves downward, so as not to affect the pressing of the concrete slab.

[0003] In the prior art, when manufacturing a concrete slab by steam pressurization, the concrete is poured into a pressing mold, and then the hydraulic cylinder is started to make the pressing plate and the guide column cooperate with each other to move into the pressing mold to press the concrete. It is only after the concrete solidifies and forms that the production of the concrete slab can be realized. However, due to the long-term repeated movement of the guide column, it is easy to have friction with the inner wall of the guide sleeve and generate a large gap, resulting in deviation. As a result, the pressing plate deviates during the up and down movement, causing the side wall of the pressing plate to easily collide with the inner wall of the pressing mold, reducing the smoothness of the pressing plate moving up and down with the hydraulic cylinder, and thus easily having an adverse impact on the normal production of the concrete slab. Summary of the Invention

[0004] The purpose of the present invention is to provide an autoclaved aerated concrete slab pressing and forming device and a forming method to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An autoclaved aerated concrete slab pressing and forming method includes the following steps: When the guide rod moves up and down with the adjustable pressing plate, it simultaneously pushes a plurality of sliding columns until a plurality of guide balls are simultaneously in contact with the outer wall of the guide rod. Thus, when the guide rod moves into the pressing mold with the adjustable pressing plate, the central axis of the guide rod and the central axis of the guide tube are completely coincident, thereby limiting the movement trajectory of the guide rod.

[0006] When the adjustable pressing plate moves out of the pressing mold, the mounting block moves in the opposite direction together with the vertical plate. At this time, the compression spring resets with the sliding of the mounting block until the compression spring is completely reset. As the mounting block moves, the mounting block applies a pulling force away from the air supply cylinder to the top of the compression spring, thereby applying a reverse pulling force to the outside of the pressure rod, and the second sealing plug resets, which is beneficial to the pressure relief inside the annular sealing tube and the sealing cylinder.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-6 , this embodiment provides an autoclaved aerated concrete slab pressing and forming device and forming method, including a base 1, a pressing die 2 and a bearing frame 3. The base 1 is fixedly installed at the bottom of the inner cavity of the bearing frame 3, and the pressing die 2 is controlled by a threaded rod and installed on the top of the base 1. Among them, bidirectional threaded rods are symmetrically installed on both sides of the base 1, and two of the side plates of the pressing die 2 are threadedly connected with the bidirectional threaded rods to adjust the size of the pressing die 2, which is beneficial to pressing concrete slabs of different sizes according to production requirements.

[0030] A hydraulic cylinder 12 is fixedly installed at the top of the inner cavity of the bearing frame 3. The bottom of the hydraulic cylinder 12 is fixedly installed with an adjustable pressing plate 4 for pressing the concrete slab. An auxiliary component for improving the pressing accuracy of the concrete slab is arranged outside the adjustable pressing plate 4. The adjustable pressing plate 4 can adjust its own size according to the size of the pressing die 2, so that the adjustable pressing plate 4 and the pressing die 2 are adapted to each other. Starting the hydraulic cylinder 12 to move the adjustable pressing plate 4 into the inner cavity of the pressing die 2 and pressing the concrete is beneficial to the production of the concrete slab.

[0031] The auxiliary component includes a guide rod 7 and a guide tube 6. Symmetrically and perpendicularly fixed to the top sides of the adjustable pressing plate 4 are guide rods 7. Through holes adapted to the guide rods 7 are symmetrically formed in the top sides of the bearing frame 3. One end of each of the two guide rods 7 far from the adjustable pressing plate 4 penetrates through the through hole and extends above the bearing frame 3. When the adjustable pressing plate 4 moves up and down, the guide rods 7 slide in the inner cavity of the through hole, which is beneficial to providing space for the up-and-down sliding of the guide rods 7.

[0032] Sliding sleeves 6 are sleeved on the outer walls of the two guide rods 7. The bottom of the guide tube 6 is fixedly connected to the top of the bearing frame 3. The guide tube 6 can play a role in limiting the sliding trajectory of the guide rod 7, improving the stability of the guide rod 7 when sliding up and down.

[0033] The adjusting component further includes a sealing cylinder 15 and a guide ball 13. A plurality of sealing cylinders 15 are fixedly inserted in a circumferential distribution on the outer walls of the two guide tubes 6. A sliding column 16 is slidably installed in the inner cavity of the sealing cylinder 15. The sealing cylinders 15 circumferentially distributed on the outer walls of the two guide tubes 6 are arranged in multiple rows along the direction perpendicular to the top of the bearing frame 3, and sliding columns 16 are installed inside the plurality of guide tubes 6.

[0034] One end of the sliding column 16 extends into the inner cavity of the guide tube 6, and a guide ball 13 is rotatably installed at the end of the sliding column 16 extending into the inner cavity of the guide tube 6. An adjusting component for adjusting the sliding column 16 is arranged outside the bearing frame 3. The diameter of the guide rod 7 is smaller than the inner diameter of the guide tube 6. When the guide rod 7 moves up and down with the adjustable pressing plate 4, it simultaneously pushes a plurality of sliding columns 16 until a plurality of guide balls 13 are simultaneously in contact with the outer wall of the guide rod 7. Thus, when the guide rod 7 moves into the pressing die 2 with the adjustable pressing plate 4, the central axis of the guide rod 7 completely coincides with the central axis of the guide tube 6, thereby limiting the moving trajectory of the guide rod 7, preventing the adjustable pressing plate 4 from shaking when moving up and down, avoiding the bottom of the adjustable pressing plate 4 from colliding with the top and inner wall of the pressing die 2, and reducing the adverse impact on the normal production of the concrete slab.

[0035] Furthermore, through the cooperation between the guide balls 13 distributed in multiple circumferential rows, the stability of the movement of the guide rod 7 can be further improved, and at the same time, the resistance during the movement of the guide rod 7 can be reduced, which is beneficial to improving the smoothness of the movement of the guide rod 7. At the same time, when the outer wall of the guide rod 7 is worn and separated from the guide balls 13, the sliding distance of the sliding column 16 can be controlled, which is beneficial to enabling the guide balls 13 to always be in contact with the outer wall of the guide rod 7.

[0036] The outer wall of the guide tube 6 is annularly distributed with a plurality of mounting holes communicating with its inner cavity. One end of each of the plurality of sealing cylinders 15 is inserted into the inner cavities of the plurality of mounting holes and fixedly connected to the inner walls of the mounting holes. The mounting holes can provide a mounting space for the connection between the sealing cylinders 15 and the guide tube 6, which is conducive to the fitting connection between the sealing cylinders 15 and the guide tube 6.

[0037] One end of each of the plurality of sealing cylinders 15 inserted into the inner cavity of the mounting hole is provided with a guide hole communicating with its inner cavity. One end of the sliding column 16 close to the guide hole penetrates through the guide hole and extends into the inner cavity of the guide tube 6. The guide hole can play a role in limiting the sliding track of the sliding column 16, which is conducive to improving the sliding stability of the sliding column 16 in the inner cavity of the sealing cylinder 15.

[0038] Example 2, please refer to Figures 1-6 , a further improvement made on the basis of Example 1:

[0039] The adjusting assembly includes an annular sealing tube 18 and a first sealing plug 17. The outer walls of the two guide tubes 6 are sleeved with the annular sealing tube 18. The inner wall of the annular sealing tube 18 is fixedly installed with a connecting tube communicating with its inner cavity. One end of each of the plurality of sealing cylinders 15 far from the mounting hole is provided with a connecting hole. One end of the connecting tube far from the annular sealing tube 18 is inserted into the inner cavity of the connecting hole. Through the connecting tube, the inner cavities of the annular sealing tube 18 and the sealing cylinders 15 can communicate with each other, which is conducive to the exchange of air inside the two.

[0040] One end of the sliding column 16 far from the guide ball 13 is fixedly installed with a first sealing plug 17 that fits against the inner wall of the sealing cylinder 15. When the adjustable pressing plate 4 moves towards the inside of the pressing die 2, the inside of the annular sealing tube 18 is pressurized. At this time, the air inside the annular sealing tube 18 quickly flows through the connecting tube into the inner parts of the plurality of sealing cylinders 15. The air pressure in the chamber formed between the inner wall of the sealing cylinder 15 close to the connecting tube and the first sealing plug 17 rapidly increases, thereby pushing the sliding column 16 towards the guide rod 7 until the outer wall of the guide ball 13 fits against the outer wall of the guide rod 7, and preventing the two from separating under the action of air pressure, which is conducive to improving the convenience of the sliding column 16 moving towards the guide rod 7.

[0041] The outer wall of the sliding column 16 is fixedly sleeved with a return spring 14. One end of the return spring 14 is fixedly connected to the inner wall of the sealing cylinder 15. The return spring 14 can apply a continuous pushing force to the sliding column 16 to move away from the guide rod 7. When the outer wall of the guide ball 13 fits against the outer wall of the guide rod 7, the return spring 14 is in a compressed state. When the adjustable pressing plate 4 is removed from the pressing die 2, the inside of the annular sealing tube 18 is depressurized until the air pressure inside the sealing cylinder 15 is equal to the atmospheric pressure. At this time, the return spring 14 resets, thus realizing the separation of the guide ball 13 and the guide rod 7, which is conducive to improving the convenience of the sliding column 16 resetting.

[0042] A gas supply cylinder 5 is fixedly installed at the top of the carrier 3. A pressure rod 9 is slidably installed in the inner cavity of the gas supply cylinder 5. A through hole communicating with its inner cavity is opened at the top of the gas supply cylinder 5. The top of the pressure rod 9 penetrates through the through hole and extends to the directly above the gas supply cylinder 5. A second sealing plug 20 that fits against the inner wall of the gas supply cylinder 5 is fixedly installed at the bottom of the pressure rod 9. The outer wall of the gas supply cylinder 5 is fixedly connected to a hose communicating with its inner cavity. The other end of the hose is fixedly connected to the outer wall of the annular sealing tube 18. When the pressure rod 9 is pressed, the second sealing plug 20 moves towards the bottom of the gas supply cylinder 5. At this time, the air between the bottom of the second sealing plug 20 and the bottom of the inner cavity of the gas supply cylinder 5 is compressed, and the compressed air flows into the inside of the annular sealing tube 18 through the hose, which is beneficial to increasing the air pressure inside the annular sealing tube 18.

[0043] Further, when the pressure rod 9 is pulled in the reverse direction to reset it, a negative pressure chamber is formed between the bottom of the second sealing plug 20 and the bottom of the inner cavity of the gas supply cylinder 5. The air inside the sealing cylinder 15 and the annular sealing tube 18 is quickly pumped out of the gas supply cylinder 5, which is beneficial to relieving the pressure inside the sealing cylinder 15 and the annular sealing tube 18.

[0044] The adjusting assembly further includes a vertical plate 10 and a mounting block 8. One end of the vertical plate 10 is fixedly connected to the top of the adjustable pressing plate 4. A plugging hole communicating with its inner wall is opened at the top of the carrier 3. The other end of the vertical plate 10 penetrates through the plugging hole and extends to the top of the carrier 3. One end of the mounting block 8 is fixedly connected to one side of the top of the vertical plate 10. When the adjustable pressing plate 4 moves up and down, the vertical plate 10 moves back and forth in the inner cavity of the plugging hole along with the adjustable pressing plate 4.

[0045] The bottom of the mounting block 8 is parallel to the top of the carrier 3, and the mounting block 8 is located directly above the pressure rod 9. A receiving hole communicating with its bottom is opened at the top of the mounting block 8. The top of the pressure rod 9 penetrates through the receiving hole and extends to the directly above the mounting block 8. An extrusion spring 11 is fixedly sleeved on the outer wall of the pressure rod 9. The top of the extrusion spring 11 is fixedly connected to the bottom of the mounting block 8. When the adjustable pressing plate 4 moves towards the inner cavity of the pressing die 2, the mounting block 8 applies pressure to the top of the extrusion spring 11, and the extrusion spring 11 is compressed under the force, thereby applying a downward pressure to the outside of the pressure rod 9, causing the second sealing plug 20 to slide towards the bottom of the gas supply cylinder 5 until the bottom of the second sealing plug 20 fits against the bottom of the inner cavity of the gas supply cylinder 5. Under the continuous pressing of the extrusion spring 11, the pressure rod 9 slides relative to the receiving hole and the mounting block 8, which is beneficial for the adjustable pressing plate 4 to slide into the inside of the pressing die 2.

[0046] Further, when the adjustable pressing plate 4 is moved out of the pressing die 2, the mounting block 8 moves in the reverse direction together with the vertical plate 10. At this time, the extrusion spring 11 resets with the sliding of the mounting block 8 until the extrusion spring 11 is completely reset. With the movement of the mounting block 8, the mounting block 8 applies a pulling force away from the air supply cylinder 5 to the top of the extrusion spring 11, thereby applying a reverse pulling force to the outside of the pressure rod 9, and the second sealing plug 20 resets, which is beneficial to the pressure relief inside the annular sealing pipe 18 and the sealing cylinder 15.

[0047] The extrusion spring 11 is arranged in a frustum-shaped structure, and the small head end is fixedly connected to the bottom of the mounting block 8, which is beneficial to improving the deformability of the extrusion spring 11 and the pressing ability of the adjustable pressing plate 4.

[0048] A pressure-bearing ring 19 is fixedly sleeved on the outer wall of the pressure rod 9. The pressure-bearing ring 19 is located between the second sealing plug 20 and the top of the inner cavity of the air supply cylinder 5. When the second sealing plug 20 resets, at this time, the pressure rod 9 always applies a pulling force away from the inner cavity of the air supply cylinder 5 to the second sealing plug 20, resulting in the top of the second sealing plug 20 always being in contact with the top of the inner cavity of the air supply cylinder 5 and deforming. It is easy to cause the second sealing plug 20 to be damaged due to long-term deformation. Under the action of the pressure-bearing ring 19, when the second sealing plug 20 resets, the top of the pressure-bearing ring 19 is in contact with the top of the inner cavity of the air supply cylinder 5, effectively preventing the second sealing plug 20 from deforming and being damaged, playing a protective role for the second sealing plug 20, and being beneficial to improving the service life of the second sealing plug 20.
